ALT 500s sap 600s and Bili of 12.5 in a 10 year old yellow cat fresh of my telemedicine lineup today. Pancreatitis, minor lobar biliary dilation and this structure located in the proximal cbd or is it a LN overlying it?? What do you think? Is this a biliary post hepatic obstruction or is this a LN linked to hepatic parenchymal disease? What would you do next?
